Abstract

The initial results of in vivo 23Na magnetic resonance imaging (MRI) of the human torso at 3-Tesla using an 8-channel dual tuned 23Na and 1H transmit/receive coil for various body applications are presented. We are able to obtain 23Na images of the human torso with 0.3 cm spatial resolution and ∼ 20 SNR in ∼15 min. These images were acquired with imaging parameters optimized under specific absorption rate limit for human scans. Because a trans-membrane sodium gradient is critical for cell survival, the ability to perform 23Na MRI of the torso in clinical settings would be useful to noninvasively detect and diagnose a number of diseases of the liver, gallbladder, pancreas, kidney, spleen and other body organs.
